Answer:

-8/45

Step-by-step explanation:

we can solve a/b by plugging in the given values and we have the new expression:

4/5 / -9/2

to solve, we can use multiply the two fractions together using KCF which stands for: Keep Change Flip. we keep the first fraction as is, change the division sign into a multiplication, and flip the 2nd fraction to its reciprocal (numerator becomes denominator and denominator becomes numerator)

4/5 / -9/2 becomes:

4/5 × 2/-9 < simply multiply the fraction

4 × 2 = 8

5 × -9 = -45

8/-45 is our new fraction. we cannot simplify this any further so this is our answer which can also be written as -8/45
